Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a mounting device for printed circuit boards used in electronic equipment.

(B) Prior Art Generally, in electronic equipment, a support member made of metal or resin is used when a printed circuit board on which various electronic components are arranged is mounted on a chassis or a main printed circuit board. Jitsukai Showa 56-
Japanese Patent No. 169577 discloses an example of the above-mentioned support member.

In the prior art, a slit and a support member insertion opening are provided on the main printed circuit board side, a protruding piece having a recess is formed on the sub printed board to be attached, and the protruding piece is inserted into the slit. After that, slide the recess to engage the sub printed circuit board, making it impossible to prevent the sub printed circuit board from coming off in the direction perpendicular to the main printed circuit board, and insert the sub printed circuit board into the support member insertion slot. A support member having a groove into which the side edge of the sub-printed circuit board is inserted is inserted to regulate the position of the sub-printed circuit board in a direction parallel to the main printed-circuit board.

(c) Problems to be solved by the invention According to the prior art, the support member is attached after the sub printed circuit board has been temporarily attached to the main printed circuit board, so it is necessary to attach the support member once when replacing parts. When removing the printed circuit board after completion of the process, it is necessary to also remove the supporting member, resulting in extremely poor workability.

(d) Means for Solving the Problems The present invention is a printed circuit board mounting device, which includes a support portion having a groove portion formed in the longitudinal direction into which the side edge of the board is inserted, and a groove portion formed at the upper end of the support portion. consisting of a bending part that can be bent toward the groove side; and a locking part that protrudes from the bending part and engages with the support part to hold the bending part in a position where the upper end of the groove is closed. It is characterized by

(E) Effect Since the present invention is constructed as described above, the printed circuit board can be stably supported, and the printed circuit board can be removed without removing the support member.

(f) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 is a resin bracket for supporting a printed circuit board, and as shown in FIGS. 1 and 2, a support part 2
and a bending part 3 which is bendably connected to the upper end of the support part 2 via a thin wall part 4.

On one side of the support part 2, a plurality of grooves 2a, 2a, 2a extending in the longitudinal direction are provided, and on the other side, first L-shaped pieces 2b, 2b with claws extending downward,
Second L-shaped pieces 2c, 2c with claws extending upward are integrally molded. Furthermore, a base 5 having protrusions 5a, 5a and screw holes 5b is integrally molded at the lower end of the support portion 2.

The bent portion 3 has groove portions 2a, 2a,
It can be bent at right angles to the side where the support part 2a is provided, and the both side edges of the bending part 3 have L-shaped parts that engage with the recesses 2d, 2d provided in the upper end of the support part 2 when the bending part 3 is bent. Hook parts (locking parts) 3a, 3a are provided.

Next, a method of attaching a printed circuit board using the bracket 1 constructed as described above will be explained.

Reference numeral 6 denotes a main printed circuit board fixed in advance to a chassis (not shown) of an electronic device, and through holes 6a, 6a for fitting projections 5a, 5a and screw mounting holes 6b are provided at predetermined positions. The through holes 6a, 6
position by inserting the protrusions 5a, 5a into a,
The bracket 1 is fixed to the main printed circuit board 6 by passing the screw 7 through the screw mounting hole 6b from the back side and screwing it into the screw hole 5b. Similarly, a bracket (not shown) of the same shape is placed at the opposite position of the bracket 1, and the side edges of the printed circuit boards 8, 8, 8 are fitted into the grooves 2a, 2a, 2a, thereby regulating the position in the left and right direction. Then, as shown in FIG.
By locking a and 3a in the recesses 2d and 2d of the support portion 2, the bent portion 3 is held in a bent state, and the upper ends of the grooves 2a, 2a, 2a are held on the side surface of the bent portion 3. Obstructed. The above-mentioned operation is the same for the other bracket placed opposite to each other.

When the bent portion 3 is in the bent state, the upper end surfaces 8a, 8a, 8a of the side edges cut out by the notched portions 12, 12, 12 of the printed circuit boards 8, 8, 8 are connected to the bent portion 3. The printed circuit boards 8, 8, 8 are brought into contact with each other, and the positions of the printed circuit boards 8, 8, 8 in the vertical direction are reliably regulated and installed without play.

Incidentally, reference numeral 9 denotes a socket attached to the printed circuit board 8, and by connecting it to a connector 10 disposed on the main printed circuit board 6, electrical connection between the two boards is established. In addition, the first and second L-shaped pieces 2
b, 2b, 2c, 2c have the function of binding and holding the lead wires 11 near the bracket 1.

(f) Effects of the invention As described above, according to the invention, it is possible to attach a plurality of printed circuit boards using a pair of opposing brackets, and in order to remove a printed circuit board that has been mounted, the bracket itself must be removed. This is easily possible by simply returning the bent portion to the unbent state, improving workability during service and having extremely high practical value.
